Abstract

De novo mutations in the WDR45 gene have been found in patients affected by Neurodegeneration with Brain Iron Accumulation type 5 (NBIA5 or BPAN), with Non-Transferrin Bound Iron (NTBI) accumulation in the basal ganglia and WDR45-dependent impairment of autophagy. Here we show the downregulation of TFEB and cell cycle impairment in BPAN primary fibroblasts. Noteworthy, TFEB overexpression rescued this impairment, depicting a novel WDR45-dependent cell cycle phenotype.<br />Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper.<br /> (Copyright © 2024 Elsevier B.V.
